Gman, I would be careful there.
I did that - bought a new home after I knew she had been unfaithful. Later she continued. She alleged I was abusive, changed the locks and got me barred from the house.
Now we face forclosure because I cannot afford her house and my new rental on my salary.

I would be careful about making big new commitments while things are in this state with your wife.

I hear the optimism in your words but that doesn't make a marriage. You need joint commitment.
